			<content:encoded><![CDATA[<p>So, what happened to all of the posts on this blog? Last year, I used the blog to post writing prompts and practice problems, which I called preambles. For many reasons, I have decided to go in a different direction this year. The old preamble posts have been deleted.</p>
<p>The Chemistry instructors at my school recognized that many of our students have forgotten basic mathematical skills that are essential to their success in math courses as well as in the chemistry course. In order to help them restore their tarnished skills, I will be starting each class with a &#8220;Miner Math Moment&#8221; which will present a single problem to be worked by each student. The students will be held accountable for doing the problems, sharing solutions, and for periodically turning in packets of the worked problems.</p>
<p>To assist me, I have installed the awesome <img src='http://s.wordpress.com/latex.php?latex=%5CLaTeX&#038;bg=ffffff&#038;fg=000000&#038;s=0' alt='\LaTeX' title='\LaTeX' class='latex' /> plugin for WordPress. This allows me to include equations that would otherwise be cumbersome to include in posts. I&#8217;m excited to have the opportunity to develop my skill with <img src='http://s.wordpress.com/latex.php?latex=%5CLaTeX&#038;bg=ffffff&#038;fg=000000&#038;s=0' alt='\LaTeX' title='\LaTeX' class='latex' />. With a bit of typing, I can generate simple, or complex equations:</p>
<p style="text-align: center;"><img src='http://s.wordpress.com/latex.php?latex=x%20%3D%20%5Cfrac%7B-b%20%5Cpm%20%5Csqrt%20%7Bb%5E2%20-%204ac%7D%7D%7B2a%7D&#038;bg=ffffff&#038;fg=000000&#038;s=4' alt='x = \frac{-b \pm \sqrt {b^2 - 4ac}}{2a}' title='x = \frac{-b \pm \sqrt {b^2 - 4ac}}{2a}' class='latex' /></p>
<p style="text-align: left;">I&#8217;m anxious to see how this works in our classes. The assumption that students necessarily retain all of their basic skills as they proceed to higher level courses is just plain wrong. Even an orchestra will start each day with basics such as scales. Professional athletes constantly practice the basics, even at the highest level of sport. Why should we expect that things would be so different for mathematics. So, here we go!</p>
